Well he can only get better from here on out. Like others have pointed out, by the end of Daredevil he improved a lot. He didn't have any real fights till recently when he beat up that pedophile.
It's not like Bruce Wayne from Batman. Bruce had dozens if not 100s of sparring partners to harness his skills. DD only had what Stick trained him to do and that didn't last too long because Stick left him.
I trust that he'll only get better.
